To 00% whom it may concern.-

Be it known that I, DUDLEY OGDEN SAYRE, a citizen of the UnitedStates,residing at South Orange, county of Essex, State of New Jersey,have invented certain new and useful Improvem cuts in Spring-Holders forGas-Globes, fully described and represented in the followingspecification and the-accompanying drawings, forming a part of the same.

The object of the present invention is to simplify the construction andoperation of the springs which are used upon gas-globe holders and towholly .conceal the springs within the periphery of the holder. Suchholders are provided with a ring upon which the flange of the globerests by its lower edge to sustain the weight of the globe and with aperipheral rim within which such flange is inserted and which operatesin practice to conceal it from view. Such globe-flange is always flaredoutwardly at its base, and I provide an exceedingly simple means ofsecuring the flange automatically within the rim by reflexing aspring-leaf from the outer margin of the rim inwardly toward thesupporting-ring at an acute angle with the axis of the holder andforming the end of such springleaf to engage the exterior of theglobe-flange adjacent to its supporting edge. When the globe-flange isapplied to the holder, it presses upon the inclined inner su rfacesofthe springs and presses them outward automatically until its edge haspassed the projecting point of the spring, when they react upon itssloping surface and lock it in the holder. The flared exterior of theflange is thus held securely in .place, while the sloping surface of theflange enablesit in many cases to push back the point of the spring-leafwhen it isnecessary to lift the globe from the holder. The projection ofthe springs inwardly from the outer margin of the globe-holder rimdistinguishes them from the springs which are commonly proj ectedoutward upon globe and chimney holders to embrace the flange of theglobe or chimney, as my springs are concealed within the holder.

The invention will be understood by reference to the annexed drawings,in which-- Figure 1 is a plan of an annular globe-holder. Fig. 2 is avertical section of the same with aof a spring, showing an alternativeconstruction'for the foot. Fig. 8 shows a part of the globe-holder rim(upon its inner side) with a spring secured thereto by small lugs. Fig.9 is a plan in section on line 9 9 in Fig. 8.

A designates the rim of the holder, and A the ring which supports theflange of the globe. The ring is shown provided with the usual arms,connected with an eye A in the center for attachment to the gas-fixture.

Three spring-tongues are shown in Fig. 1 riveted to the rim A andextended first upwardly and then downwardly toward the ring A. Thetongue is formed in one piece of spring metal, as shown in Fig. at, andis bent, as shown in Fig. 2, into three partsa foot 17, a flexible leafB, and an inclined lip 13'. The leaves B are sloped inwardly and areproportioned to press elastically upon the flange O of the globe D,which, as is common in such constructions, is outwardly flared from theglobe. The lip 13 upon each spring is sloped outwardly like the flangeO. The lower edge of the flange when inserted within the sloping sidesof the leavesB and pressed downwardly operates to force them out untilthe bottom edge of the flange passes the junction of the leaves B andlips B, and when the flange makes contact with the ring A, as shown inFig. 2, the leaves are moved inward sufficiently for the lips B toengage the outer flaring surface of the flange and hold the same withinthe rim A by elastic pressure. The

sloping surfaces of the lips afford a seat upon which the flange presseswhen it is liftedfrom the globe and serve to force the leaves 13outwardly until the flange is drawn clear of the springs. Three of thesprings are shown in Fig. 1, which are in practice made of suitablestrength and elasticity for holding the globe securely from displacementby accidental jars. In practice the flange of the globe is insertedunder two of the springs when applying the globe to the holder and thenpressed downwardly upon the remaining spring, which yields until theflange is fitted completely with the holder, as shown in Fig. 2.

The construction shown in Figs. 1 and 2 is especially adapted for theconversion of ordinary globe-holders, of which large numbers are in use,provided with screws to grasp the globe-flange, as such screws may bereadily removed and the spring-leaves riveted to the rim A, thusproviding the holder with an automatic clamp for the globe.

In the manufacture of new globe-holders the springs may be formedintegral with the rim A, which obviously necessitates the use of alarger piece of sheet metal to form the holder. To use as small a pieceof sheet metal as possible, the springs mayin such case be formedwithout the lips B, as the ordinary globe-flangc is suitably inclined topress the spring outwardly without the use of such lip. Figs. 5 and 6show such a construction for the spring. In this construction thespring-leaf is formed as a tongue projected upwardly, as represented bythe dotted lines I) in Fig. 6, and then bent downwardly and slopedinwardly, as shown in Fig. 5, terminating a sufficient distance abovethe ring A to press within the neck of the flange C. Such tongues yieldthe same as those shown in Fig. 2 when the flange O is presseddownwardly into the holder; but as the free end of the leaf isunprovidcd with the lip B the release of the flange from the springrequires an inclination upon the flange, which makes it capable ofslipping past the point of the-spring when lifted. \Vhere the flange isnot formed with a suitable inclination, it maynot be dislodged from thesprings by merely lifting the globe, but requires in such case means forretracting one of the springs to release the flange. To free the springfrom the flange, a stud 6 may be projected from the spring outwardlythrough the rim A to draw one of the springs outwardly when lifting theglobe from the holder.

It is obvious that the integral spring may be formed with the lip B, thesame as is shown in Fig. 2, and the necessity of a stud the holderinstantly and without operating any of the clamping devices by thefingers.

Figs. 8 and 9 illustrate a modification of the means that maybe used tosecure the spring upon the globe-holder, the sprin gbeing shown in Fig.8 in vertical section at the top to expose the foot-piece only, which isrepresented with a notch c in each side, as may be formed by cutting theblank where indicated by dotted lines 0 in Fig. 4. Fig. 9 shows aportion of the rim of the holder, in section on line 9 9 in Fig. 8,intersecting the foot-piece I) through the notches and showing lugs abent inwardly from the rim at a suitable distance to fit the notches andadapted to be clenched down upon the front side of the foot. The lowerlug is shown thus clenched and the upper one in the position in which itwould be bent when the spring is applied to the rim. The spring may, ifdesired, be made of wire instead of sheet metal and bent to correspondwith the form of the leaf B and lug B and provided with a foot ofsuitable character to attach to the globe-holder by rivets or lugs.

I am aware that springs have been attached to gas-globe holders forsecuring the globeflange therein; but my invention differs from thosepreviously used in having the springleaf projected inwardly from theouter edge of the peripheral rim A, by which it bends from a pointadjacent to the edge of such rim, and its flexibility increases fromsuch edge toward its inner point, which presses upon the globe-holder.By this construction a very short spring can be secured by a single footto the globe-holder and projected within the rim A, where it is whollyconcealed.

With a globe-flange of the ordinary inclination, as is shown in Fig. 2,the spring serves to admit and release the flange automatically, theaddition of the inclined lip B facilitating the admission and release ofthe flange in case it has an excessive outward flare.

Having thus set forth the nature of the invention, what is claimedherein is 1. The globe-holder having the ring A with central eye forsupporting it upon the gasfixture as usual, and the peripheral rim A toinclose the globe-flange, such rim having a series of springs reflexedinwardly from the outer margin of such rim toward the ring A at an acuteangle with the axis of the holder to conceal them within its rim, andadapted to engage a flaring globe-flange, substantially as herein setforth.

2. The globe-holder having the ring A with central eye for supporting itupon the gasfixture as usual, and the peripheral rimA to inclose theglobe-flange, such rim having a series of springs reflexed inwardly fromthe outer margin of such rim toward the ring A at an acute angle withthe axis of the holder to conceal them within its rim, and the mostprojecting point of such spring being formed to engage the exterior ofthe globe-flange adjacent to its supporting edge, substantially asherein set forth.

8. The globe-holder having the ring A with central eye for supporting itupon the gasfixture, as usual, and the peripheral rim A to inclose theglobe-flange, such rim having a series of springs reflexed inwardly fromthe outer margin of such rim toward the ring A I In testimony whereof Ihave hereunto set at an acute angle with the axis of the holder my handin the presence of two subscribing to conceal them within its rim, andprovided witnesses.
